Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for using JustAnswer.com
I am sure this is on, but I have to ask. Do you have a Service Engine Soon light on?
NO ENGINE LITE ON
Ok, I have a few tricks up my sleeve then to see if we can isolate this
First off, when this happens does it seem to not want to rev over 2k rpms? or it doesn't rev period?
WHEN STARTING THE ENGINE, IT STALLS AFTER 3 SECONDS AND YOU NEED TO START IT AGAIN. THEN YOU TRY TO KEEP IT RUNNING BY DEPRESSING THE GAS PEDAL, BUT IT DOES NOT REV UP. IT SEEMS LIKE THERE IS NO GAS GOING TO THE ENGINE. IT JUSTS LABORS AND STALLS.
You can't even rev it?
Does it bog?
NO IT DOESN'T REV UP AND BOGS
Lets try this
How handy are you?
Oh how many miles on the car?
What I am going to ask you to do isn't to tough. It's actually fairly easy.
Open the drivers door and when it's open, when you look towards the door hinges you will see 3 plastic caps on the body.
Pop these caps off.
Under these caps there are three 14 mm bolts. Get a ratchet and tighten up these 3 bolts. You will most likely find they are some what loose. Only make these bolts snug. Do not over tighten.
OK WERE DOING SO AS WE SPEAK
I can hang on while you do this,
JUST TO CLARIFY THEY ARE 12MM AND THEY ARE TIGHT
I thought they were 14's. That could be the Maxima.
Ok, Good that they are tight.
How many miles on the car?
Is it always hard to start?
I am talking about the start and stalling? How often does it do this is what I meant. All the time?
NO JUST STARTED TO HESITATE A MONTH OR SO AGO BUT TODAY WAS THE FIRST TIME IT STALLED
I LET IT SIT FOR A FEW HRS AND TRIED TO START IT AN IT STALLED 3 TIMES
Oh, so this problem is in the beginning type stage.
WHAT DO YOU MEAN BY THAT
This is the first time it really only gave you this problem
Before this it just had a hesitation every once and a while?
YUP FIRST TIME...JUST TRIED TO START IT AGAIN.;.NO IDLE KEEPS STALLING
So it's doing it now!
Unplug the MAF sensor and see if it starts and idles. Do not give it gas
just see if the car starts and idles.
WHERE IS THAT SENSOR LOCATED
this test may cause a service engine soon light
This is located on the back side of the top part of the air filter box
OK ILL CHKN IT
OOPS CHK IT OUT NOW
ENGINE LIGHT APPEARS BUT RUNNING SMOOTH WITHOUT STALLING..NOW WHAT
So that worked?
BUT FOR HOW LONG
That is just a test
Turn the car off
and plug it back in
Then disconnect the negative battery cable to for 10 mins to clear the codes
It's a good chance you will need a MAF sensor
90% of the time the MAF ( Mass Air Flow ) sensor heated element which meters the air so the computer can add the proper fuel mixture has fallen out of spec. Not enough to cause a Service Engine Soon light but enough to cause the Air and fuel Mixture to be so off it can cause Stalling, poor acceleration, won't rev over a certain Rpm, and running issues. I would have the Air and Fuel mixture readings checked to verify. Checking the voltage will not show the fault, the air and fuel mixture will. If found to be bad, do not replace with a After Market one. After market MAF sensors never seem to work properly. There heated element doesn't work right which can cause 02 sensors to flat line and have you chasing you tail trying to figure out what is wrong. So the only way to correct this issue if you do have a bad MAF sensor is to replace it with a OEM.
IF ITS DEFECTIVE CAN IT BE LEFT UNPLUG (TEMPORARILY)
JUST SO ITS DRIVEABLE
It's not recommended
When it's unplugged it's unsafe to drive
This was only a test I had you perform
THE TRUCK RUNS WITHOUT IT DOES THAT MEAN ITS THE PROBLEM
When that is unplugged it goes to default rich which is 75%
when it should run at 100%
